SHELLS  OF  MAINE./''  A  :     \\.  {  ';'. 


A  Catalogue  of  the  Land,  Fresh-water  and  Marine  Mollusca  of 
Maine,  by  NORMAN  WALLACE  LERMOND. 

INTRODUCTORY. 

No  general  list  of  Maine  shells — including  land,  fresh-water 
and  marine  species — has  been  published  since  1843,  when  Dr. 
J.  W.  Mighels'  list  was  printed  in  the  Boston  Journal  of  Natural 
History. 

Dr.  Mighels  may  be  called  the  "Pioneer"  conchologist  of 
Maine. 

By  profession  a  physician,  in  his  leisure  hours  he  was  a  most 
enthusiastic  collector  and  student  of  all  forms  of  molluscan  life. 

Enthusiasm  such  as  his  was  "contagious"  and  he  soon  had 
gathered  about  him  a  little  band  of  active  students  and  collectors. 
Of  these  Capt.  Walden  of  the  U.  S.  Revenue  Cutter  "Morris" 
was  dredging  in  deep  water  and  exploring  the  eastern  shores 
and  among  the  islands,  and  "by  his  zeal  procured  many  rare 
species ;"  Dr.  Ray,  principal  of  the  Insane  Hospital  at  Augusta, 
collected  the  land  and  fresh  water  forms  in  the  vicinity  of  that 
city;  Dr.  Milliken  of  Unity  in  Waldo  county  and  Dr.  True, 
principal  of  the  academy  at  Monmouth  in  Kennebec  county, 
collected  in  those  counties. 

These  collectors  were  pursuing  their  favorite  "hobby,"  in 
the  late  thirties  and  early  forties. 

In  1851  Dr.  William  Stimpson,  the  noted  conchologist  of 
Massachusetts,  published  his  "Shells  of  New  England,"  which 
included  many  Maine  records.  His  "Synopsis  of  the  Marine 
Invertebrata  of  Grand  Manan,"  containing  a  list  of  the  mollusca 
dredged  by  him  off  that  island,  was  published  in  1854;  and  in 
1860  the  Smithsonian  Institution  published  his  "Check  List"  of 
New  England  Shells,  Nos.  i  to  6. 

In  the  early  fifties,  J.  W.  Chickering,  Jr.,  and  Edward  S. 
Morse  became  students  of  conchology  under  Dr.  Mighels. 

In  1854  J.  W.  Chickering,  Jr.,  published  his  "List  of  Marine, 
Fresh  water  and  Land  Shells,  found  in  the  immediate  vicinity 
of  Portland."

\*  /\  As  Ett  Mig&ds  had  gathered  his  band  of  collectors  around  him 
'  "in  the^fdrties/sO  Morse  and  Fuller  had  several  earnest  collectors 


wjtb\them  in  the  early  sixties;  of  these  Rev.  E.  C. 
s,  k  iUjkvVtsaltst  minister  of  Portland,  now  professor  in 
Tufts  College,  and  Major  John  M.  Gould  of  that  city,  did  much 
collecting  in  Cumberland  and  Oxford  counties.  While  neither 
Gould  nor  Bolles  published  anything  on  Maine  mollusca,  they 
both  furnished  data  and  material  and  aided  Professor  Morse  in 
the  preparation  of  his  "Pulmonifera  of  Maine,"  as  he  acknowl- 
edges in  the  preface  to  and  throughout  that  work. 

In  1861  Charles  B.  Fuller  of  Portland,  who  was  attached  to 
the  State  Scientific  Survey,  under  the  directorship  of  Ezekiel 
Holmes,  and  who  was  associated  with  A.  S.  Packard,  Jr.,  in  his 
trip  to  the  eastern  Maine  coast,  dredged  and  collected  the  off- 
shore forms  along  the  coast  from  Eastport  to  Casco  Bay  and 
the  land  species  on  the  islands  of  that  bay.  The  results  of  this 
expedition  were  embodied  in  his  "Report  on  Marine  Zoology," 
and  published  in  the  secretary  of  agriculture's  report  for  1862, 
pp.  129  to  133. 

In  1864  Prof.  Edw.  S.  Morse  published  a  finely  illustrated 
catalogue  of  the  land  and  fresh-water  species  of  the  State,  with 
full  descriptions  and  notes  on  distribution. 

To  Prof.  Addison  E.  Verrill,  a  native  of  Maine,  now  director 
of  the  Connecticut  Academy  of  Arts  and  Sciences,  we  are 
indebted  for  much  of  our  knowledge  of  the  deep-sea  forms. 
He  spent  seven  summers,  from  1865  to  1872,  at  Eastport  and 
was  attached  to  the  government  dredging  expedition  of  1873. 
The  results  of  his  work  on  the  Maine  molluscan  fauna  have 
appeared  in  various  scientific  publications  and  government 
reports.  His  "Explorations  of  Casco  Bay"  was  published  in 
the  U.  S.  Fish  Commissioner's  Report  for  1874,  and  in  1882  a 
complete  list  of  marine  species  added  to  the  fauna  of  the  New 
England  region  during  the  past  ten  years,  in  Trans.  Conn. 
Academy  Arts  and  Sciences,  vol.  5,  pp.  447  to  588. 

The  first  list  of  Maine  shells  ever  published  was  that  of  Dr. 
Charles  T.  Jackson,  State  Geologist,  which  appeared  in  an 
appendix  to  his  first  report  on  the  Geology  of  Maine,  Augusta, 
1837.  In  this  list  Dr.  Jackson  enumerates  38  marine,  9  fresh- 
water and  3  land  species,  or  a  total  of  50  species.  Dr.  Mighels' 


1843  list  contains  113  marine,  38  fresh-water  and  23  land 
species,  or  a  total  of  174  species.  Morse  in  his  1864  list  gives 
55  fresh-water  and  50  land  species,  or  a  total  of  105  species. 
In  his  published  lists  from  1874  to  1884,  Verrill  enumerates 
196  marine  species  and  7  varieties.  While  the  present  list 
includes  256  species  and  13  varieties  of  marine,  82  species  and 
20  varieties  of  fresh-water  and  65  species  and  5  varieties  of 
land  shells,  thus  showing  quite  a  growth  in  our  knowledge  of 
the  mollusca  of  Maine. 

In  working  up  local  faunas  the  following  field  naturalists  have 
done  excellent  work  and  added  much  to  our  knowledge  of  the 
shells  of  Maine :  Olof  O.  Nylander  in  Aroostook ;  Anson  Allen 
at  Orono ;  John  A.  Allen  in  the  towns  of  Hebron  and  Buckfield, 
Oxford  county;  Arthur  H.  Norton,  curator  of  the  Portland 
Society  of  Natural  History,  in  Cumberland  county;  Dr.  W.  C. 
Kendall  at  Freeport  and  Eastport;  Rev.  Henry  W.  Winkley 
at  Eastport,  Islesboro,  Wiscasset,  Old  Orchard  and  Casco  Bay; 
Edwin  P.  Went  worth  and  wife  at  Newcastle,  Lincoln  county 
and  South  Portland,  Cumberland  county;  Prof.  J.  S.  Kingsley 
of  Tufts  College,  in  Casco  Bay;  Dwight  Blaney,  dredging  in 
Frenchman's  Bay,  seasons  from  1901  to  1906;  John  B.  Hender- 
son, Jr.,  and  George  H.  Clapp  at  Kennebunkport  and  at  Bar 
Harbor;  H.  S.  Colton  at  Mt.  Desert;  Edward  W.  Roper  in 
Cumberland,  Piscataquis  and  Waldo  counties ;  Henry  Jackson, 
Jr.,  at  North  Haven,  Penobscot  Bay;  Charles  W.  Johnson, 
curator  Boston  Society  of  Natural  History,  at  Deer  Isle  in 
Moosehead  Lake ;  and  the  author  in  Knox  county. 

Many  of  the  above  collectors  have  published  in  local  lists  the 
results  of  their  collecting,  for  the  main  part  in  the  several 
volumes  of  the  Nautilus.  In  1901  Prof.  Kingsley's  "Prelim- 
inary Catalogue  of  the  Marine  Invertebrata  of  Casco  Bay"  was 
published  in  vol.  2  of  the  proceedings  of  the  Portland  Society 
of  Natural  History.  This  list  includes  154  species  of  marine 
mollusca.  In  1904  Blaney's  "List  of  Shell-bearing  Mollusca  of 
Frenchman's  Bay,  Maine,"  was  published  in  vol.  32,  No.  2.  of 
the  Proceedings  of  the  Boston  Society  of  Natural  History,  and  a 
supplemental  list  in  Nautilus,  vol.  19,  p.  noiii. 

The  State  has  been  only  partially  explored  as  yet  conchologi- 
cally;  Casco,  Eastport  and  Frenchman's  Bays  having  been  the 


most  thoroughly  explored  for  marine  species;  and  Aroos- 
took,  Cumberland,  Oxford,  Knox,  Penobscot,  York  and  Han- 
cock counties  for  land  and  fresh-water  species.  Little  or  no 
collecting  has  been  done  in  Androscoggin,  Franklin,  Sagadahoc, 
Washington,  Waldo  or  Somerset  counties.  183  species  have 
been  reported  from  Casco  Bay,  146  from  near  Eastport,  137 
from  Frenchman's  Bay  and  81  marine  species  from  Penobscot 
Bay.  The  following  table  will  show  at  a  glance  the  distribution 
of  species  by  counties,  including  all  known  records  of  land  and 
fresh-water  species  in  Maine.

It  is  with  the  hope  of  stimulating  further  research,  especially 
in  those  counties  where  little  or  no  work  has  been  done,  and 
thus  extending  our  knowledge  of  the  distribution  of  the  shells  of 
Maine,  that  this  list  is  published.  Hoping  to  publish  a  revised 
list  later  on,  we  shall  be  glad  to  receive  specimens  or  records  of 
shells  from  all  sections  of  the  State.

Ostrea  virginica,  Gmelin. 

Ostrea  canadensis,  Lamarck. 
Ostrea  borealis,  Stimpson,  1851. 
(The  common  oyster.) 

This  shell-fish  was  common  in  the  tidal  rivers  and  bays  of  the 
Maine  coast,  as  the  Indian  shell  heaps,  notably  the  one  on  the 
banks  of  the  Damariscotta  river,  in  the  town  of  Damariscotta, 
and  dead  shells  still  to  be  found  in  the  beds  of  the  rivers  elo- 
quently attest.  The  cause  of  their  dying  out  on  the  coast  of 
Maine  has  not,  to  our  knowledge,  been  satisfactorily  explained. 
Several  attempts,  at  different  times,  to  restock  the  rivers  have 
ended  in  failure,  with  the  possible  exception  of  a  bed  in  Sheeps- 
cot  river,  Lincoln  county.  There  are  specimens  from  this 
river  in  the  museum  of  the  Portland  Society  of  Natural  History 
that  were  taken  alive  by  Mr.  G.  M.  Brown,  the  date  of  collection 
not  being  given.  Rev.  Henry  W.  Winkley  informs  me  that  he 
has  in  his  collection  a  specimen  of  ostrea  virginica  from  the 
Sheepscot  river  at  a  place  called  Sheepscot  bridge,  about  two 
miles  above  Wiscasset.  He  further  says:  "There  is  a  small 
bed  of  living  oysters  there  and  I  understand  they  have  survived 
from  anciest  times." 
Pecten  gibbus  var.  borealis,  Say. 
Pecten  irradians  of  authors. 
(The  common  or  eastern  scallop.) 

Portland  harbor  (C.  B.  Fuller  collection  in  Portland 
museum ;  in  Indian  kitchen  midden,  shores  of  New 
Meadows  river,  Brunswick,  (Prof.  Leslie  Lee). 


Pecten  islandicus  (Muller). 
(The  Arctic  scallop.) 

Casco  Bay  to  Eastport. 
Pecten  magellanicus,  Gmelin. 

Pecten  tenuicostatus,  Mighels,  1842. 

Chlamys  clintonius,  Verrill. 

(The  Maine,  Great  or  Giant  scallop.) 

Casco  Bay  to  Eastport. 

This  is  the  largest  Pecten  on  the  Atlantic  coast,  attaining  a 
very  large  size,  a  specimen  from  Portland  Harbor,  and  now  in 
the  Portland  museum,  measuring  6  11-16  in  length  by  73-16  in 
width.  The  abductor  muscle,  called  by  the  fishermen  the  "eye" 
or  "heart,"  of  the  scallops,  both  the  common  and  Maine  species, 
is  largely  used  for  food.  "Scalloping,"  or  taking  the  scallops 
in  dredges,  is  no  inconsiderable  industry  on  the  Maine  coast, 
pursued  by  many  fishermen. 
Pecten  pustulosus,  Verrill,  1873. 

Gulf  of  Maine,  115  to  150  fath.  (Verrill). 
Pecten  subimbrifer,  Verrill  and  Bush.

Gulf  of  Maine,  121  fath.  (Verrill). 
Anomia  simplex,  d'Orbigny. 

Anomia  ephippium,  Gould,  1870. 
Anomia  electrica,  Gould,  1870. 
Anomia  glabra,  Verrill,  1873. 

Casco  Bay  to  Eastport. 
Anomia  aculeata,  Linne. 

Casco  Bay  to  Eastport. 
Mytilus  edulis,  Linne. 

(Common  black  or  blue  mussel.) 

This  edible  shell-fish  is  found  in  beds,  at  low  water  mark,  alt 
along  the   Maine  coast.     And  while  it   lacks  the  flavor  of   the 
clam,  it  is  quite  palatable. 
Mytilus  edulis  var.  pellucidus,  Pennant. 

(Rayed  or  translucent  mussel.) 

Found  in  company  with  the  type  species,  but  not  nearly  as 
abundant.

Of  the  edible  qualities  of  this  clam,  Dr.  Mighels,  in  his  1843 
list,  remarks  as  follows :    "It  is  used  by  a  few  as  an  article  of 
food,  but  it  is  tough  and  indigestible  and  I  have  known  some 
to  be  seriously  injured  by  eating  it."

While  we  have  no  Maine  record  for  this  species,  there  is  no

"Buzzard's  Bay  to  New  York"  and  of  bisuturalis,  "Mass.  Bay;" 
while  of  seminuda,  he  gives  the  range  as  from  "Mass.  Bay,
